Remote camera

A digital camera transmits a still picture from a remote location whenever it receives a cell-phoned command or external trigger. The Cellular Lookout is ideal for surveillance and visual monitoring or remote sites. The weather-proof solar-and-battery-powered camera allows installation without wiring. Transmission of additional analog, digital, or positional data from the remote site is also possible.

Tracks of heavy ions 'imprinted' in lithium fluoride crystals. At the top, spot tracks observed under a fluorescence microscope in plates perpendicular to the heavy ion beam. At the bottom, the ion tracks in the parallel oriented plate (the blurring at both ends of the trace is an artifact of the depth of focus of the microscope). False colors.

Lithium fluoride fluorescent crystals track high-energy heavy ions such as iron

In comparison to previous crystals such as aluminum oxide, LiF crystals also require a less expensive microscope for analysis.

FIGURE 1. The tip of a 30,000-core optical fiber bundle is shown next to an Australian 5 cent coin for scale (left) and a zoomed-in image (right) reveals a small region of the fiber bundle facet (dashed red box in left). Each core is roughly 2 µm in diameter and separated from its neighbors by an average of 3.3 µm.

Fiber-optic Components: Fiber-optic bundles provide 3D stereo imaging

With each fiber acting as an independent pixel, coherent fiber bundles transmit more information than just a 2D representation of an image; specifically, the spatial light field faithfully encodes 3D stereo data.
